A grocery store carries the following items. There are two main categories of food - conventional and organic ingredients - and four food groups. The data are shown in the following table.
Food Groups
Food Categories Grains Fruits Vegetables Meat Total

If all of the items were accidentally displayed together without a sticker or label to mark their origin, what is the probability that you select a grain, fruit, or meat in your grocery basket, regardless if it's conventional or organic? First compute for yourself the row (i.e., n1+, n2+), column (i.e., n+1, n+2, n+3, n+4), and overall (i.e., n++) totals, to aid in answering the question.
